EXCLUSIVE! Demi Lovato ‘Lost Respect’ For Joe Jonas After He Brought New GF Ashley Greene On Their Tour!

Can you imagine having to go on tour with your ex-boyfriend…and then watch him start dating another girl right in front of you? No wonder Demi is over Joe!

Demi Lovato is handling her awkward romantic situation like a true champ. Not only is she traveling around the country performing with ex-boyfriend, Joe Jonas, but the Disney starlet has had to suffer the indignity of watching Joe fall in love with someone new – he brought new GF Ashley Greene on tour!

“You know, I don’t have advice for anybody on that. You gotta brush it off,” Demi, 18, told HollywoodLife.com exclusively when we asked her what advice she’d give to other girls in her situation.

“I think there’s a certain level of respect that’s lost when that happens, but you can’t do anything about it other than to just keep going and be glad you have someone in your life that you can think about and spend your time with,” she added.

Joe, 21, and Demi became best friends when they shot their Disney film, Camp Rock, together in 2007. They started dating earlier this year, but sadly, after only two months of dating, broke up in May. Now, Joe has ditched his purity ring (literally) and has been spotted canoodling all around the world this summer with Twilight actress Ashley Greene.

We cannot even imagine being in Demi’s shoes right now…she’s handling the entire situation way more maturely than we ever could!
